A revival of a forty-year old kit, The TAP is a 4-key, touch-sensitive pad soldering kit from Boldport.
At a time when powerful processors are so cheap and much of their functionality is left unused in a typical application, it’s delightful to look back to hobbyist electronics projects from forty years ago, and admire the optimised design and the skill of those who created them.
In the first edition of Elektor magazine in English, December 1974, appeared a lovely touch-activated circuit. Boldport re-created it for the enjoyment of those who may appreciate the elegance of the design today.
Note: requires through-hole soldering!
The TAP was project #5 of the Boldport Club.
